So when conversing with an old Motörhead relative of mine. He exclaimed he would never attach his temp. gauge to the spark plug where it was intended, but would rig it to one of the close inside head fins or a head bolt. He said it would give a more accurate read of what's really go on temp wise. Although it might take a little modification I liked that idea rather than getting a spark plug temp reading which would give more spikes in temp. What do you all think......?
